    GPIO issue

    @qq.com

      Hi!

         

         First of all, I  am testing GPIO'speed in the GpioApp firmware.I found that output need take 0.75us.Because I need more fast

         

      speed(frequent). I want to know how to improve it

         

        Besides, I set input with interrupt enabled for both edges,I found that it need take  about 14us. I want to know how to decrease interupt time

         

      Last , I want to know more information about GPIO register.May you send me information of GPIO register if you can ?

         

      Thank you very much!

           Hi,

             

          FX3 SDK 1.2.1 now includes the source code for firmware APIs.You can refer to the file cyu3pgpio.c which includes the source code of various GPIO APIs for register level implementation.
